Powder Metallurgy Characterization of Thermoelectric Materials for Selective Laser Melting

Batista N., El Desouky A., Crandall J., Wang S., Yang J., LeBlanc S., The George Washington University, US

Thermoelectric materials are semiconductors capable of converting heat into electrical energy. Traditional manufacturing of thermoelectric devices involves machining and assembly steps which limit device geometries, result in material loss, and introduce parasitic thermal and electrical [...]

Effect of matrix components with low thermal conductivity and density on performances of cement-EPS/VM insulation mortar

Chen M., Wang S., Lu L., Zong W., Zhao P., Gong C., University of Jinan, CN

Cement-EPS/ vitrified microsphere (VM) insulation (CEV) mortar was prepared by using suphoaluminate cement as cementitious material, EPS and VM as insulation aggregates. The performance of matrix without insulation aggregates not only could determine the mechanical [...]

An Integrated Biometric Platform for Evaluation of Targeted Drug Delivery

An Electrodeposition Method for Preparing (Ni-Cu) /(Cu-Ni) Multilayers on magnesium alloy from ionic liquid

Guo J., Guo X., Guo J., Guo X., Dong J., Wang S., Gong J., Zhu R., Ding W., Shanghai Jiao Tong University, CN

Abstract A single bath of ionic liquid electrodeposition method has been developed for the preparation of (Ni-Cu)/(Cu-Ni) multilayers on AZ91D magnesium alloy. The technique has been used to make multilayers with a composition of (92.47at.%Ni-7.53at.%Cu) [...]

Analytic potential model for asymmetricunderlap gate-all-around MOSFET

Wang S., Peking University, CN

An analytic potential model for undoped cylindrical gate-all-around (GAA) MOSFET with asymmetric gate underlap is developed in this paper. This model is derived by solving the Poisson’s equation with the parabolic potential approximation, channel length [...]

Magnetic Nanotag-based Immunoassay for Multiplex Mycotoxin Detection

Mak A.C., Osterfeld S., Yu H., Wang S., Davis R.W., Jejelowo O.A., Pourmand N., Stanford University, US

Rapid, sensitive and multiplexed measurement is vital in molecular diagnostics such as cancer diagnosis and pathogens detection. While highly specific and sensitive, traditional immunochemical assays such as enzyme-linked immunosorbent assays (ELISAs) often require expensive read-out [...]

Non-destructive 3D Imaging of Nano-structures with Multi-scale X-ray Microscopy

Wang S., Lau S.H., Tkachuk A., Druewer F., Chang H., Feser M., Yun W., Xradia, Inc., US

X-ray microscopy offers a unique combination of large penetration depth, high resolution, and high sensitivity to elemental composition. When combined with computed tomography (CT) techniques, the full three-dimensional structure of a sample can be obtained [...]

The Dynamic Performance of a Micro-machined Coriolis Flow Meter

Clark C., Wang S., Cheesewright R., Brunel University, UK

The dynamic performance of micro-machined Coriolis flow meters Summary The performance of a prototype MEMS mass-flow meter developed by ISSYS was investigated using the Brunel University Virtual Coriolis Meter facility. The flow meter comprises a vacuum sealed [...]

Protein can act as unique template to assemble gold nanoparticles in a linear fashion

Bhattacharya R., Patra C.R., Wang S., Lu L., Yaszemski M.J., Mukhopadhyay D., Mukherjee P., Mayo Clinic, US

Nanoparticles of metals possess unique chemical, electronic, optical and magnetic properties from their bulk counterpart because of the quantum size effects. The spatial orientation and arrangement of nanoparticles is important in the realization of technologically [...]
